What the data for this category looks like
Energy metals research report data mainly comes from public statistics of non-ferrous metal industry associations, in-depth reports from securities research institutes, real-time quotes and industry trends from commodity information platforms. Update cycles cover daily, weekly, and irregular in-depth releases. Each single document includes industry supply and demand data, corporate production capacity indicators, price trend snippets, policy summaries, and other content. Fields include "lithium carbonate grade", "production capacity ten thousand tons/year", "spot price yuan/ton", and others. Some documents have embedded chart attachments.
What constraints do these characteristics impose on the vector models and indexing link
The high-frequency daily data feature of energy metals research reports requires the indexing system to support incremental updates, to avoid additional overhead from full reconstruction. The presence of structured fields and unit identifiers requires the index to retain field metadata, to ensure business semantics are not lost during vector matching. Dense professional terminology in research reports requires the vector model to have domain semantic alignment capabilities. Documents with embedded charts further require the vector model to support encoding and indexing of multimodal content.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
embedding_model | multimodal-embedding-v1 (for research reports with charts) or text-embedding-v3 (for plain text research reports) | Covers text and multimodal content, adapts to the mixed text and image structure of energy metals research reports |
chunk_size | 800–1200 characters | Balances semantic integrity of professional terms and table snippets, avoids semantic fragmentation or dimensional redundancy |
enable_incremental_index | Enabled | Adapts to high-frequency daily updated data, avoids resource consumption from full index reconstruction |
index_refresh_interval | 15 minutes | Matches the update rhythm of energy metals industry dynamics, ensures timeliness of retrieval results |
top_k | Top 10–15 results | Accurately recalls core data snippets, avoids redundant results interfering with retrieval experience |
vector_db_batch_size | 32–64 entries | Balances batch import efficiency and vector database load, adapts to the processing scale of single batch research reports |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing values.
Three common mistakes
- Phenomenon: Vector recall results do not match embedded chart data from research reports. Cause: A plain text vector model is selected to process energy metals research reports with charts, and multimodal vector encoding capability is not enabled.
- Phenomenon: Indexing processes time out continuously when importing research reports in batches, and the log returns the
ETIMEDOUTerror code. Cause: The incremental index switch is not configured, and the vector import batch size is set too large, leading to database load overload. - Phenomenon: The indexing configuration displays as empty in the docker-compose deployment environment, and custom indexing rules cannot be loaded. Cause: The
INDEX_CONFIG_PATHenvironment variable is not configured in docker-compose.yml, and the local configuration file is not mounted to the corresponding directory in the container.
How to verify the configuration is correct
- Upload a single energy metals research report with charts, trigger the vector encoding process, and check if the returned vector results include encoding identifiers for multimodal content.
- View the indexing system monitoring panel, confirm that incremental indexing tasks are automatically triggered at the preset interval, and there are no abnormal prompts for full reconstruction.
- Search for energy metals professional terminology, and verify that the recalled results include structured data and corresponding field information from the research reports.
- Check the running logs of docker-compose containers, and confirm that there are no error messages related to
INDEX_CONFIG_NOT_FOUND.
